Abstract (en)
[origin: EP1092618A2] The invention provides a motor-driven assist unit capable of improving the performance of the maintenance, such as inspection and repair, of the motor-driven assist unit, and reducing the number of components of a unit case for containing the motor-driven assist unit. A motor-driven assist unit contains an electric motor for generating an assist-power in response to a leg-power inputted to a crank shaft, wherein the assist-power and the leg-power are synthesized and the resultant power is transmitted to a drive wheel. The motor-driven assist unit is characterized by including a unit case 10 formed by fastening a left case half 10L for rotatably supporting a left end of a crank shaft 101 to a right case half 10R for rotatably supporting a right end of the crank shaft 101; and a unit cover 10A which is mounted to a side opening portion, formed in one of the case halves (10L, 10R), in such a manner as to cover the inside of the motor-driven assist unit exposed from the side opening portion; wherein hanger portions 90, 91, and 92 for fastening the unit case 10 to a vehicle are formed only on the one (10L) of the case halves (10L, 10R). <IMAGE>
